两种消毒方法对X射线防护服消毒效果的比较

目的比较使用伽玛医用消毒湿巾与75%乙醇对X射线防护服表面消毒的效果，为选择合理的消毒方法提供依据。方法选取X射线防护服62件，其中手术室30件，导管室32件。随机分为试验组和对照组，每组各31件。试验组采用伽玛医用消毒湿巾、对照组采用75%乙醇对X射线防护服表面进行擦拭消毒，比较两者的消毒效果、消毒待干时间及使用成本。结果试验组与对照组细菌菌落数均值在消毒前分别为2.38 CFU/cm2及2.36 CFU/cm2，合格率分别为80.64%和83.87%。两组消毒后细菌培养均未检出细菌。试验组X射线防护服消毒平均待干时间为（352.35±9.93）s，低于对照组的（676.13±10.62）s，差异有统计学意义（t=123.98，P＜0.01）。试验组消毒X射线防护服每次的成本比对照组节省29.60%。结论使用75%乙醇与伽玛医用消毒湿巾对X射线防护服消毒效果均可靠，与75%乙醇相比，伽玛医用消毒湿巾对X射线防护服无腐蚀、消毒待干时间短、节省使用成本。

Comparison of disinfection effect of two disinfection methods on X-ray protective clothing

ObjectiveTo compare the effect of GammaTM wet wipes and 75% alcohol on the disinfection of X ray protective clothing， and provide reference for choosing rational disinfection methods.Methods62 pieces of X ray protective clothing were selected, 30 were from operating rooms, 32 from catheterization room. Protective clothing were randomly divided into trial group and control group, each had 31 pieces. Trial group disinfected clothing with GammaTM wet wipes, control group disinfected clothing with 75% alcohol, disinfection effect, drying time, and cost between both groups were compared.ResultsAverage bacterial colony counts in trial group and control group before disinfection were 2.38 CFU/cm2 and 2.36 CFU/cm2 respectively, qualified rates were 80.64% and 83.87% respectively. Bacteria were not detected in both groups after disinfection. The average drying time in trial group was shorter than control group（［352.35±9.93］ s vs［676.13±10.62］ s，t=123.98，P＜0.01）. The cost of disinfecting X ray protective clothing in trial group was 29.60% less than control group. ConclusionEffect of GammaTM wet wipes and 75% alcohol on disinfecting X ray protective clothing are both reliable, compared with 75% alcohol, GammaTM wet wipes are without corrosion, have shorter drying time, and save more cost.
